I've an aironet sap2602 that behaves strangely: dhcp negotiation is allowed only for some clients and not for others.
In detail, AP is connected to a captive portal system, so everybody is allowed to connect by itself, but you have to pass captive portal in order to go on internet.
Captive portal is also dhcp server.
On captive portal I see dhcp transaction only for some clients (the one that work fine), for other clients I don't see any negotiation, either successful or not.
I have done a packet sniffing with wireshark, so I can tell it's not a Captive Portal problem, but something between AP and client, since I don't see traffic from the mac address of the faulty client.
My question is: how can I debug this situation on the AP?????
Thanks a lot
